What Is Reverse Osmosis Water Filter?
The Reverse Osmosis process, also called the RO, is a water purification method that manages to remove solids such as salts and other big particles using a semipermeable membrane. The tap water is pushed through this membrane with pressure and, during this process, the big particles are filtered away from the resulted water that is more pure. This method is used in both industrial and individual water filtration systems as it proved to be cost-effective and efficient in removing pathogens like bacteria and viruses besides the other type of contaminants already mentioned.
Today’s water filter systems that implement RO promote various stages of water filtering and different types of filters, thus allowing the resulted solution to be up to 99% contaminants-free. This is actually one of the main features you should consider when purchasing a water filter system: the type of filters and the number of stages the water goes through in order to be cleaned.
How Does Reverse Osmosis Work?
Reverse osmosis is not just a technology used by the water filter under your sink; it actually has many applications in the industry and is extremely helpful in getting drinking water out of salt waters. The principle is quite simple and it only requires a semipermeable membrane that will filter off the contaminants (salt, bacteria, viruses, other big particles) and pass (almost) pure water on the other side. In order for this to work, the water must be pressurized when passing through the membrane.
The membrane is usually comprised of three layers: a polyester base, a polysulfone layer that comes on top of the base, and a polyamide layer that is only a few microns thick on top of the first two. The polyamide layer is the one that actually acts as a barrier against various pollutants while the other two act as support. The water is forced through the filters that contain the membrane and, while it flows through, it leaves behind most of the contaminants.
The result water’s purity level can be influenced by a few factors like:
- The water pressure – in order to have a great filtration, water must go through the membrane with a certain pressure level. The membrane is built to withhold high pressure but it won’t perform so well in conditions of low pressure;
- The temperature;
- The type of solids present in the water – if the filtration capacity of the membrane has been reached, you must change the filter;
- Each filter is equipped with a certain type of membrane and this also influences the end result.
What Does Reverse Osmosis Remove?
Through reverse osmosis, solid particles like salts are removed from the drinking water. Also, you must know that, with the contaminant particles, RO also removes most minerals as they are usually bigger than the water molecule.
As a summary, RO removes the following types of particles:
- Ions and metals like arsenic, selenium, silver, chloride, zinc, iron, lead, and more;
- Big particles like asbestos;
- Radium and Uranium;
- Big bacteria and viruses;
- Some microorganisms.
While the method is very efficient in clearing the water from most pollutants, you should also know that it will not remove harmful contaminants like dissolved gases, bacteria and viruses with a mass smaller than the water molecule’s.
Systems that implement a series of filters are going to deliver water of higher quality due to the fact that the water is going to be pushed through successive membranes, thus lowering the risk of filter degradation.
Does Reverse Osmosis Remove Fluoride?
Concerns regarding fluoride were raised ever since scientists proved that, in high concentrations, it may damage the brain or it may weaken the bone structure and lead to fractures in older people. Also, children exposed to high concentration of fluoride may develop bad teeth. The fluoride used to be added in water in order to strengthen the teeth and improve the general oral health in population, but according to new regulations and discoveries, it’s best to avoid constant exposure.
Fluoride is actually a type of salt, resulted from the combination of the fluorine element with various minerals presented in the environment. So, are all public waters contaminated with fluoride components? The water may be contaminated when passing through certain mineral deposits in the ground or during the filtration process in the processing plant. Also, there are communities that simply add fluoride into water for the health benefits they believe it brings.
The safe levels of fluoride in drinking water were established in 1974 when the Congress approved the Safe Drinking Water Act. The maximum level of contaminants that a person can be exposed to, during his/her lifetime, when it comes to fluoride, is 4.0 mg per liter. Anything that goes over this number may be dangerous for the health of the population. Also, the recommended level is actually 2.0 mg per liter, but these limits are non-enforceable.
Even today, in some areas, fluoride is intentionally added in the drinking water in order to help population fight cavities and other oral problems. As long as the maximum level of concentration established by the Congress is maintained, the fluoride won’t have any effects over the general health.
Since fluoride is actually a type of salt and its mass is usually bigger than the mass of the water molecule, the membrane installed in the filters manages to catch around 93% of the particles. Of course, if the filter is of lower quality, the quantity of fluoride caught during the reverse osmosis process will be smaller. This is one of the most important reasons why it’s always best to invest in high quality filters.
Reverse Osmosis Pros and Cons
As you surely concluded by now, reverse osmosis is a very efficient method for water purification in both the industrial and individual environment. Still, every amazing method has its problems, so let’s make a short comparison of pros and cons and see which one scores more points.
- The possibility to obtain drinking water in areas where most waters are salty or heavily contaminated with solids;
- Most filters will deliver 97% pure drinking water, free of most contaminants. This water is usually safe to drink by both adults and children;
- The resulted water usually tastes great and it will be crystal clear. This is due to the fact that the water is almost completely pure and it doesn’t have any odors;
- The method doesn’t require any energetic consumption as the water is naturally pressured into pipes, before passing through the membrane;
- Most water filters that use this method are cost-effective;
- The system is easy to maintain and it only require a regular change of filters;
- Removes most bacteria and viruses.
- The method also removes most minerals and the end result is almost completely demineralized water;
- Small bacteria and microorganisms that have a mass smaller than the one of the water molecule will pass through the membrane;
- You need 2 gallons of water to produce 1 gallon of purified water which means that about half of the water quantity will be wasted;
- Many pollutants used in the water processing plants are smaller than the water molecule, thus remaining in the drinking water.
